Granular compacts, their production and use

A compacted granular product (G) produced by the steps of:

• providing a mixture of at least one water-soluble dye or optical brightener (A), with an extender (B), and optionally, at least one member selected from the group consisting of:
• at least one hydrophilic surfactant (C), further additives (D), to produce a mixture (M);
• dry-compacting said mixture (M) to obtain a dry-compact (m);
• granulating said dry-compact (m) to obtain a granulated dry-compact (gm);
• and
• treating said granulated dry-compact (gm) with a dust-binding oil (E) to produce a compacted granular product (G).
